Re: Long Story short

Hope u have the tag similar to this -

<html:form name="myForm>
<% int n= 0; %>

<logic:iterate id="someid"     name="myForm"    property="productList" >
// Here iterate tag is just acting as for loop .No use of scripting variable
"id"
    <html:text  name="myForm"    property="productList[n].productName"  />
// this will call getProductList ( index) followed by getProductName ( )
    <html:text  name="myForm"    property="productList[n].productPrice"  />
<% n ++ %>
</logic:iterate>
</html:form>

Here n is the index variable .    No need of using the **indexed iterate tag
** in above case .

Then have methods like

class myForm extends ActionForm {
private Vector  productList ;        //  contains list of  Product objects .
public Product getProductList(int index) {
    return (Product)productList(index);
}

public void setProductList( Vector list) {
    productList =  list ;
}
}

The class Product  implements Serializable {
private String productName ;
private String productPrice;

 //   getter and setters
public String getProductName ( ) {
    return productName ;
}
public void setProductName(String name ) {
    this.prodctName = name ;
}
public String getProductPrice () {
    return productPrice ;
}
public void setProductPrice(String price) {
    this.productPrice = price ;
}

}
